The U.S. Secret Service, with international law enforcement, seized and removed the website of Russian crypto exchange Garantex, citing alleged ties to sanctioned Russian banks and criminal groups.

“We are fighting and will not give up,” the note said, accusing Tether.
In April 2022, the U.S. Department of the Treasury’s Office of Foreign Assets Control working with the FBI and Department of Justice, among other U.S. agencies, and German police sanctioned Garantex.
OFAC alleged that more than $100 million in transactions on the exchange were “associated with illicit actors and darknet markets including nearly $6 million from the Russian RaaS gang Conti and approximately $2.6 million from Hydra,” a darknet market.
